Abstract: Systems, apparatuses and methods to apply computer capabilities to tabletop games including board games such as the game of chess. In one embodiment, a camera connected to smart glasses repeatedly feeds real-time images of a board game to a computer vision system that identifies the game, breaks the game board into elementary segments (e.g., individual squares), and identifies game pieces located on the segments. A game state may be determined by reference to a listing of pieces on each segment and a rule set. In addition, hints and/or other guidance may be provided to the player. Moreover, the game state may be described in a standard notation and/or may be transmitted to remote locations for use by other players.

Abstract: A method for switching the use of a shared set of wireless I/O devices between multiple computers. The method of one embodiment comprises receiving a wireless request at a first machine to switch control of a device to a second machine. Control of the device is relinquished at said first machine. A token is transferred from the first machine to the second machine. Wireless control of the device is established at the second machine.
